the forward end of the slide 19 a screw 33 is threaded therein, andsurrounding the barrel of said screw is' a torsion-spring 14 connectedat one extremity 35 to said slide19,

and having a tip 36 bearing against the enjtension of the carrier 4. Anunyielding head 37 is attached to the top of the screw .33, and belowsaidhead is a loose sleeve 38,

which' surrounds the upper partof the torsion-spring.-

A lpin 39 coacts with ratchet-teeth 40 on the knurled sleeve 38, and asWill be obvious when the spring is put under tension its tendency willbe y,automatically to force thesupvrectangular seats/43 in which restangular projections 44 from a steady-rest 45 having a concave shoe 46,and also having an arm 47 held in place by the depending'nose orprojection 41 of the slide 19.

From what has been stated it will be seen that as the Work 48diminishes'in diameter under the action of the reducing-tool the shoe 46will-be held i'n constant, rigid con. tact with said world-and Withoutany yielding action of `the steady-rest by the means j described.

Our invention is not limitedl tothe precise details or mechanicalfeatures ofthe structureshown for changes may be vmade in the variousdetails thereof without departure from the invention and 'equivalentsmay be employed in connection with. the means for positively holding thesupport for the steadyrest in unyielding' engagement with the Work.

Having thus described our invention what We claim is: 1

1. The combination, with a swinging vsupport, of a slide4 mountedthereon; a steadyrest mounted. for unyielding movement on said slide;and means for unyieldingly causing an advance of the slide, and forholding the steady-rest against the work under unyielding pressure.

2. The combination, wi'th a support mounted for swinging movement, andwith a slide on said support, of a steady-rest removably mounted on saidslide; means for rigidly holding the steady-rest in position against thework, and-for preventing detachment of said steady-rest from theV slide;means for advancing the slide under unyielding pressure; and means forforcing said steadyrest against the work also under unyielding pressure.,A

3. The combination, 'with a support mounted for swinging movement, andwith a movable carrier on said support, of a steady-rest removably andrigidly mounted on said carrier; means applied to the carrier forholding the steady-'rest in position against the work; means forpreventing detachment of said steady-rest from the slide; and means foralso forcing said steady-rest in a substantially vertical planeagainstthe work under unyielding pressure.

4. The combination, with a support, and

with ya ca'rrier on said support, of a steady-' 5. 'l'he combination,with a carrier having angular bearings, of a steady-rest'havingprojections fitted and conforming to saidbearings; and a device mountedonl the carrier, and engaging a part of the steadyrest for 'preventingsaid steady-rest from" being forced out of position when in engagementwith the Work.

6. The combination, with acarrier having angular-bearings, of asteady-rest having 'lateral projections 'conforming tosaid bearin sl anarm ro'eetino from saidstead said arm; and means for forcing the carrierand the steadyreso against the work under unyielding pressure, and forcausing it to follow up the reduction of the work.

7. The combination, with a carrier 'having angular'bearings, ofafsteady; rest having lateral projections conforming to said bearings;an arm projecting from saidsteadyrest; a device on the carrier forengagingl rest; a device on the carrier for engagingsaid arm; means forforcing the carrier and the steady-restagainst the work under un--yielding pressure, and for causing it to follow up the reduction .of thework;A and lmeans acting in a vertical plane upon the carrier, andserving to force the steady-rest under unyielding pressure, said meansbeing located at an angle to the means' first speci-' fied.'

8. The combination, with a support, of a screw gv means for autmaticallyt rning the screwy to advance `the carrier uxide unyield# ing pressure;asteady-rest; a device pro-' jecting from the carrier, and havinganangular seat for l'said steady-rest; an angular projection on the'steady-rest; and means for preventing displacement of the steady-restwhen in engagement with the work. i

9. The combination, with a carrier, and with a slide mounted thereon.said slide having angular bearings at its inner end; a steady-resthaving angular projections mounted in said bearings. and also having aninwardlyv projecting arm: means for advancing the slide under lmvielding'pressure; and means bearing against the support for causingtheslide move in.a substantially vertical plane, said means also Vbearingnected to the support; a torsion .spring; means for winding said,spring;- means controlled by the torque of said spring for caus-v ingthe movement. of the slide under unyielding pressure; and a steady-restrigidly' connected with the slide.

1l.'l The combination, with a support, of a slide' mounted on saidsupport ;4 a screw connected' to the support; a torsion J spring; meansfor winding said spring; means controlled by the torque of said springfor 'causing movement of t he slide underunyielding pressure; asteady'irest rigidly'connected with the. slide; and means for'preventing said steady-rest from displacement when in en gagement withthe Work. l

12. The combination, with a pivoted support. and with a device carriedthereby, having bearingsfofa steady-'rest having` prejee` tions'mount-edin said bearings, and incapable of rotation therein.; -a screw connectedwith the support; a torsion spring surrounding the screw; and meansactuated by said torsioinspring for holding the steady-rest against the'work under unyielding pressure.

13. The combination, with a pivoted support, and with a slide mountedfoi-'movement thereon, of a screw eonneetedto saidv support; atorsionspringals-o conneeted to said support; means for actuating?r thescrew, and to which the torsion-spring is attached; n steady-re;--:tcarried by the slide. and automatieally held against the `work by thetorque of said spring.

14. The combination, with al carriage,l Dfva support pivoted theretofaslide movableimon' said support; a screw connected to 'said s 1pport; atorsion-spring attached atfone part tothe support,v and at another pointto an element of the screw; 'a steady-rest rigidly mounted on thesilppoi'tgandmeans for pres Venting-the movement of said steady-restwhen in engagement with the Work.

l5. The combination, with a pivoted support, of a slide mounted thereon;mechanism involving a screw and a torsion-spring for producing a forwardmovement of the slide under unyielding pressure.; abase.; ,anscrewthreaded into said base; a torsion spring on said screw; mechanism forcontrolling the tension of said torsion-spring; a 'steady-restunyieldingly mounted on the slide; Y and means for preventing the-displacement `of said steady-rest 'While' in Contact with the Work.

1G. .The combination of a movable members one ofvWh-ich is supported byanotherv`l and onejoif said members con stituting a carrier or supportfor avsteady@ rest, and'v means for 'independently feeding said membersto advance the steady rest and .for unyieldingly preventing movement ofeach of them in' a direction opposite to their feeding' movements. y
